Help, can you help please?

As an assignment I have to learn enough Ada and write the following parallel 
program:

Find the prime numbers in the first 100 numbers (1, 2, 3, ... , 99, 100) 
using the Sieve of Eratosthenes.  Write down all numbers from 2 to 100.  
The first number in the list (2) is a prime.  Strike off all multiples of 2.  
On the remaining list the next number (3) is a prime.  Strike off all 
multiples of 3, and so on.

Task 1 - Produces numbers from 2 to 100

Task 2 - outputs the first number it gets, deletes multiples of 2 from the
         list and passes the remaining list to Task 3.

Task 3 - outputs the first number it gets, deletes multiples of 3 from the
         list and passes the remaining list to Task 4.

Task n - outputs the first number it gets, deletes all multiples of the first
         number and passes the remaining list to the next task.

Can anyone let me have any code similar to this that I can adapt.  Unfortunately
I'm running out of time!!!

Thanks.

Hehe  -- I remember an interesting implementation of this that I saw
on the TeleSoft Ada compiler for AU/X (!!!!) (Pretty sure it was
TeleSoft).

    Seeing as how they are requiring "Top Secret" security clearance
    (something not all that common in industry) one would presume this
    is some sort of Government Job - possibly a government contract.
    It sure sounds like the government is abandoning Ada. What ever
    happened to that business of requiring cost justification for
    language choice in the wake of abandoning "The Mandate"?

    I've heard the arguments for dropping The Mandate and they sure
    sound convincing. But I've been afraid that the message would be:
    "Ada is so terrible that even we, who created it, don't want to
    have anything to do with it anymore." (It doesn't matter what you
    *say* - it matters what people *hear*!)

    Well I'm glad we've made inroads in other areas - particularly
    education. Maybe those inroads will sow the seeds for future
    growth and people will be willing to drop their preconceived
    notions and judge the language on its merits. It would be ironic
    if a new generation of programmers were to be coming out of school
    with Ada experience and end up trying to justify to a contract
    officer why he shouldn't be demanding they do the project in C++
    because Ada is the technically & financially smarter choice.
